This is a continuation of prior co-pending patent application Ser. No. 10/727,418, filed Dec. 4, 2003.
The present invention relates to electronic trading of securities. In some embodiments, the present invention relates to methods and apparatus for processing and routing securities orders.
Existing securities order processing and routing systems may make routing decisions based on current order book conditions at various potential order destinations such as securities exchanges, market makers or specialists, and/or ECNs (Electronic Communication Networks). ECNs are private electronic networks that allow for placement of securities trading orders and are fully automated to match orders and set prices for trades without the intervention of market makers. Order routing decisions, whether to securities markets, market makers or ECNs, may also be based at least in part on historical data that has been compiled for the order destinations. However, routing decisions based only on current order book conditions and/or on historical data that has customarily been used may not optimize trading performance.
To address the foregoing, embodiments of the present invention concern a method, an apparatus, and a medium storing processor-executable process steps to determine during a trading session an attribute of an order destination other than a quoted security price and an order size for an order destination, and to determine during the trading session, based at least in part on the determined attribute, at least one of: (a) whether to route an order to the order destination, and (b) a proportion of the order to allocate to the order destination.
As used herein and in the appended claims, “order destination” refers to any one or more of a securities exchange, a market maker and an ECN; and “trading session” includes one or both of (a) a calendar day, and (b) a period during a calendar day during which a market or ECN is open for trading.
In some aspects, the determined attribute may be one or more of: (a) an average response time exhibited by the order destination during the trading session in regard to orders for a particular security; (b) a percentage of total market volume in the particular security handled during the trading session by the order destination; (c) a degree to which the order destination is overfilling orders for the particular security during the trading session; (d) an average amount of time that the order destination offered a best price for the particular security relative to other order destinations; (e) a percentage of the trading session during which the order destination offered a best price for the particular security relative to other order destinations; (f) a number of times during the trading session at which the order destination offered a best price for the particular security relative to other order destinations; and (g) an average amount of time required during the trading session for the order destination to match a best price offered for the particular security by another order destination.
Thus, in some aspects, an order routing decision may be based on information, in addition to order price and size of orders pending on an order destination, that is dynamically updated during a trading session. With routing based on such dynamically updated information, order routing may be performed in an automated yet insightful manner to take advantage of dynamically changing market behaviors that are not directly reflected in current order book conditions. Improved order execution, in regard to either or both of price obtained and speed of execution, may thereby be achieved.
With these and other advantages and features of the invention that will become hereinafter apparent, the invention may be more clearly understood by reference to the following detailed description of the invention, the appended claims, and the drawings attached hereto.
In general, and for the purposes of introducing concepts of embodiments of the present invention, data regarding one or more attributes of a number of order destinations is dynamically updated during a trading session. The data relates to information other than the current contents of order books of the order destinations. The data is used during the same trading session in making routing decisions among the order destinations. For example, an order may be apportioned among the order destinations on the basis of a calculation that uses the dynamically updated data regarding the order destination attributes.
Features of some embodiments of the present invention will now be described by first referring to
As depicted, trading network 100 includes a trading system 102 in communication with one or more customer(s) 104, a plurality of order destinations 106, a source 108 of order destination data, and one or more operator devices 109 (only one shown). Trading system 102, in some embodiments, includes an execution core 110, a router 112 and an order destination data analysis and storage capability 114. Execution core 110 may be any trading execution software, systems and/or devices which are configured to receive customer orders and process them to execute orders on behalf of customers. In some embodiments, execution core 110 may function to timestamp orders when received and to assign an order identifier or sequence number to each order.
Router 112 may be configured to receive an order from execution core 110 or to receive information about an order and to make a determination as to how the order is to be routed. That is, the router 112 determines an order destination or order destinations to which the order is to be routed, and if the order is to be divided among two or more order destination, the router 112 determines the respective proportions of the order to be allocated to the order destinations. Details of the operation of router 112 will be discussed below. The router may execute the routing decision that it makes, or may provide information concerning the routing decision to the execution core 110 to allow the execution core 110 to execute the order in accordance with the routing decision made by router 112.
Data analysis and storage capability 114 operates to receive from the data source 108 data concerning the order destinations 106 and to maintain and update databases (to be discussed below) concerning the order destinations based on the data received from data source 108. As will be seen, the databases may also reflect data derived from direct experience of the trading system 102 in dealing with the order destinations 106. The data analysis and storage capability 114 may receive at least some of the data for the databases, and may analyze the data and update the databases, on a dynamic basis during each trading session. The databases are accessible to router 112 and the routing decisions made by router 112 may be based, at least in part, on the data in the databases.
Although a single trading system 102 is shown in
Each of the devices of trading network 100 may be formed of components or other devices capable of performing the various functions described herein. For example, a customer device 104 may be a computing device such as a Personal Computer (PC), a laptop, a telephone, or other device associated with a customer. As used herein, the term “customer” may refer to, for example, an individual or other entity that buys and sells securities (and pursuant to some embodiments of the present invention, options; for purposes of this disclosure and the appended claims “securities” will be understood to include options). For example, a customer operating a customer device may be a broker or other entity desiring to purchase or sell securities using features of embodiments of the present invention. The broker or other entity may be operating on behalf of the ultimate purchaser or seller of the securities.
An order destination 106 may include any computing device(s) operated by or on behalf of one or more order destinations. Each of the order destinations may be in communication with other devices described herein, such as the data source 108, using techniques known in the art. In general, the data source 108 may receive information from the order destinations 106 upon the occasion of each order received by the order destinations and/or after the completion of each trading transaction. Each order destination 106 may include one or more operator terminals allowing specialists or traders at the order destination to respond to orders received and to complete execution of an order pursuant to its terms.
Operator device 109 may, for example, be constituted by a computer terminal or by a computing device such as a PC or a laptop in communication with the trading system 102.
As used herein, devices (e.g., trading system 102, operator device 109, order destinations 106, customer devices 104 and data sources 108) may communicate, for example, via one or more communication networks. For example, some or all of the devices may be in communication via an Internet Protocol (IP) network such as the Internet. Some or all of the devices may be in communication via other types of networks such as an intranet, a Local Area Network (LAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), a proprietary network, a Public Switched Telephone Network (PSTN), and/or a wireless network.
According to some embodiments of the present invention, communication between some or all of the devices of trading network 100 may be via temporary computer communication channel (e.g., a logic path through which information can be exchanged). In other words, the communication channel between various devices may be established and discontinued as appropriate. For example, trading system 102 may exchange information with one of the order destinations 106 only when communication is necessary to transmit an order for execution by the order destination 106 or to receive confirmation from the order destination 106 that the order was executed.
According to some embodiments, some or all of the devices may communicate with other devices via a public computer communication network. That is, at least a portion of the communication network may be accessed by devices other than the devices depicted in
In other embodiments, the devices of
Reference is now made to
Processor 200 may be constituted by one or more conventional processors, and may, for example, comprise RISC-based and other types of processors. Processor 200 operates to execute processor-executable process steps so as to control the elements of trading system 102 to provide desired functionality.
Communication device 202 may be used to facilitate communication with, for example, other devices (such as customer devices 104, order destinations 106, data source 108 and operator device 109). Communication device 202 is therefore preferably configured with hardware suitable to physically interface with desired external devices and/or network connections. For example, communication device 202 may comprise an Ethernet connection to a local area network through which trading system 102 may receive and transmit information over the World Wide Web.
Input device 206 may comprise, for example, a keyboard, a keypad, a mouse or other pointing device, a microphone, knob or switch, an infra-red (IR) port, a docking station, and/or a touch screen. Output device 208 may comprise, for example, a display (e.g., a display screen), a speaker, and/or a printer. Input device 206 and output device 208 may together constitute or be constituted by operator device 109 (
Storage device 204 may comprise any appropriate information storage device, including combinations of magnetic storage devices (e.g., magnetic tape and hard disk drives), optical storage devices such as CDs and/or DVDs, and/or semiconductor memory devices such as Random Access Memory (RAM) devices and Read Only Memory (ROM) devices.
Storage device 204 stores one or more programs 210 for controlling processor 200. The programs 210 comprise processor-executable process steps of trading system 102, including process steps that constitute processes provided in accordance with principles of the present invention, as described in more detail below. Processor 200 performs instructions of programs 210, and thereby operates in accordance with the present invention. In some embodiments, programs 210 may be configured, at least in part, as a neural network or other type of program using techniques known to those skilled in the art to achieve the functionality described herein. In some embodiments, programs 210 may provide the functionality of each of the major components of trading system 102, including execution core 110, router 112 and data analysis and storage capability 114 (
Any or all process steps of trading system 102 may be read from a computer-readable medium, such as a floppy disk, a CD-ROM, a DVD-ROM, a Zip™ disk, a magnetic tape, or a signal encoding the process steps, and then stored in storage device 204 in a compressed, uncompiled and/or encrypted format. Processor-executable process steps being executed by processor 200 may typically be stored temporarily in RAM (not separately shown) and executed therefrom by processor 200. In alternative embodiments, hard-wired circuitry may be used in place of, or in combination with, processor-executable process steps for implementation of processes according to embodiments of the present invention. Thus, embodiments of the present invention are not limited to any specific combination of hardware and software.
Storage device 204 also stores databases, including, for example, order destination attribute databases 212 relating to individual securities and “generic” order destination attribute databases 214, which store data concerning attributes of order destinations with respect to a plurality of and/or all securities traded at an order destination. For example, in some embodiments, the generic order destination attribute databases may contain data that represents characteristics of all trading activity on the order destinations, or of all trading activity in securities that are not represented in the individual security databases 212. In some embodiments, respective dedicated databases 212 may be maintained for perhaps 100 or 200 leading securities for a given securities market. Routing decisions for these securities may be based at least in part on data stored in the respective dedicated databases 212 for those securities. Routing decisions for other securities may be based at least in part on data stored in generic databases 214.
Other databases may also be provided (e.g., order and execution data may also be stored in storage device 204). Examples of the order destination attribute databases 212, 214 are described below in conjunction with
There may also be stored in storage device 204 other unshown elements that may be necessary for operation of trading system 102, such as an operating system, a database management system, other applications, other data files, and “device drivers” for allowing processor 200 to interface with devices in communication with communication device 202. These elements are known to those skilled in the art, and are therefore not described in detail herein.
Referring now to
The database illustrated in
Order destination attribute database 212 or 214 (as depicted in
As depicted, the table defines a number of fields 300-314 for each of the entries. Each entry corresponds to a respective order destination to which orders may be routed by the trading system 102, and contains data indicative of attributes of the respective order destination, as indicated by data received and/or gathered by the trading system 102. The fields specify: an order destination identifier 300, a response time 302, a fill rate 304, a percentage of total volume 306, data 308 indicative of current order book size (outloud volume—“OLV”) less transactions already in queue to the respective order destination (OLV-Q); “overhit” points data 310; “triggers” data 312, and overall speed rating data 314.
The order destination identifier 300 may be a commonly used abbreviation or acronym that identifies the respective order destination. Although the order destination identifiers 300 are represented, for purposes of illustration in
The response time 302 is data, in units of seconds, indicative of an average time elapsed between routing of an order to the respective order destination and either time of execution or receipt of confirmation from the order destination that the order was executed. This information may be generated and updated by the trading system 102 in real time based on its transactions with the various order destinations. The period over which the average response time is calculated for purposes of field 302 may, in some embodiments, be the most recent hour of trading, with updates every five minutes to provide a moving average. As one alternative, the average response time may be calculated over the last three trading sessions.
The fill rate 304 represents the average extent to which orders routed to the respective order destination for the security or securities in question have been filled over a period of time. For example, an order that is totally filled is considered to have exhibited a 100% fill rate. An order that was only half filled (e.g., 100,000 shares routed and 50,000 filled) is considered to have exhibited a 50% fill rate. The period over which the average fill rate is calculated may be, in some embodiments, the immediately preceding trading session plus the current trading session up to the present time. This information may be generated and updated by the trading system 102 in real time based on its transactions with the various order destinations.
The percentage of volume 306 corresponds to the percentage of total volume in the security or group of securities in question handled by the respective order destination relative to the total volume in the security or group of securities. This information may be compiled from market data received via the data source 108. In some embodiments, for example, the percentage of volume 306 may be calculated based on the average daily volume of the order destinations over the last five trading days.
The OLV-Q data 308 may be calculated on the basis of the total size of book orders shown for the respective order destination, less the size of orders already queued for routing from the trading system to the respective order destination. One, two, or more levels of the order destination's book may be taken into account. This information may be derived from a combination of current order book information received from the data source 108 and information generated by the trading system 102 in regard to transactions with the order destinations. OLV-Q data 308 may indicate current, real-time status of the order destinations. In some embodiments, OLV-Q data 308 may be maintained only for databases 212 dedicated to individual securities.
“Overhit” data 310 may be derived from an average extent to which orders have been “overfilled” by the respective order destination and may also be based in part on the size of the orders overfilled. In some embodiments no overhit data may be indicated for an order destination showing less than 1,000 shares on its order book. An order may be considered “overfilled” when the size of the order exceeded the size of the orders on the order destination book, but the order was nevertheless filled in excess of the size of the orders on the order destination book. Thus “overhit” data may be indicative of hidden liquidity at the order destination. In some embodiments, the overhit data may be compiled over a period that corresponds to the immediately preceding trading session plus the current trading session up to the current time. This information may be derived from a combination of order book information received from the data source 108 and information generated by the trading system 102 in regard to transactions engaged in by the trading system with the order destinations.
The “triggers” data 312 indicates preference factors that may be entered into the database 212 or 214 by the proprietor of the trading system 102 to implement preferences for routing orders to one or more of the order destinations. The triggers may represent agreements entered into between the order destinations and the proprietor of the trading system 102, and/or subjective judgments by the proprietor of the trading system 102 about the merits of the order destinations, and/or may be based on technological capabilities or other objective characteristics of the order destinations. As will be seen, trigger data essentially implements weighting factors to favor certain order destinations in routing decisions.
The speed rating data 314 may be calculated and updated in real time on the basis of the data in fields 302-312. In some embodiments, for a particular order destination all of the data in fields which may positively correlate to speedy order execution (e.g., the data in fields 304, 306, 308, 310 and 312) may be multiplied together, and the resulting product may then be multiplied by the inverse of the data in fields (if any) which may negatively correlate to speedy order execution (e.g., the data in field 302). The resulting product may be, for example, divided by a factor of 1,000 or 10,000, and truncated to an integer, to yield the speed rating data 314 for the respective order destination.
It will be appreciated that the above procedure for calculating speed rating data 314 effectively provides equal weights to all of the factors represented by the data in fields 302-312. Alternatively, the data in fields 302-312 may be combined additively rather than multiplicatively, and a weighting factor may be applied to one or more of the factors represented by the data in fields 302-312 to generate the rating data 314. Other procedures for generating rating data from one or more types of order destination attribute data may alternatively be used.
Some or all of the order destination attributes corresponding to the fields 302-312 may be eliminated and/or replaced with other attributes of order destinations. To give just one example, the fill rate data 304 may be replaced with or supplemented by data that reflects “fill quality”, i.e., the extent to which orders are filled on the order destination in question at a better price than an order limit price.
Referring now to
The database illustrated in
Order destination attribute database 212 or 214 (as depicted in
As depicted, the table defines a number of fields 400-412 for each of the entries. Each entry corresponds to a respective order destination to which orders may be routed by the trading system 102, and contains data indicative of attributes of the respective order destination, as indicated by data received and/or gathered by the trading system 102. The fields specify: an order destination identifier 400, average time at NBBO (national best bid or offer) data 402; percentage of time at NBBO data 404, number of times at NBBO data 406, average time required to join NBBO 408, “triggers” data 410 and overall price rating data 412.
The information in field 400 may be the same as the information described above in connection with field 300 shown in
The average time at NBBO data 402 may indicate, for the respective order destination, the average amount of time the best order on the book of the order destination matched the NBBO price as measured per occasion when the best book order matched the NBBO price. Although not indicated in the drawing, separate statistics may be maintained for matching the bid and asked NBBO. This data may be generated by the trading system 102 by suitable analysis based on real-time data received via the data source 108. In some embodiments, the average may be compiled over the most recent ten trading sessions. Thus this data may represent an average amount of time that the respective order destination offered a best price for the particular security relative to other order destinations.
The percentage of time at NBBO data 404 may indicate, for the respective order destination, the percentage of a specified period of time during which the best order on the book of the order destination matched the NBBO price. Again, separate statistics may be maintained for matching the bid and asked NBBO, although such separate statistics are not illustrated in the drawing. Also, the data 404 may be generated by the trading system by suitable analysis based on real-time data received via the data source 108 and may be compiled, in some embodiments, over the most recent ten trading sessions. Thus this data may represent a percentage of at least one trading session during which the respective order destination offered a best price for the particular security relative to other order destinations.
The number of times at NBBO data 406 may indicate, for the respective order destination, a tabulated total of occasions on which the best order on the book of the order destination matched the NBBO price. Once more, separate statistics may be maintained for matching the bid and asked NBBO, although such separate statistics are not illustrated in the drawing. Also, the data 406 may be generated by the trading system by suitable analysis based on real time data received via the data source 108 and may be compiled, in some embodiments, over the most recent ten trading sessions. Thus this data may represent a number of times during at least one trading session at which the respective order destination offered a best price for the particular security relative to other order destinations.
The average time to join NBBO data 408 may indicate, for the respective order destination, an average duration of the occasions on which the best book order price of the order destination does not match the NBBO price. Again, separate statistics may be maintained for time to join the bid and asked NBBO, although such separate statistics are not illustrated in the drawing. Also, the data 408 may be generated by the trading system by suitable analysis based on real time data received via the data source 108 and may be compiled, in some embodiments, over the most recent ten trading sessions. Thus this data may represent an average amount of time required during at least one trading session for the respective order destination to match a best price offered for the particular security by another order destination.
The information in field 410 may serve the same function as the information discussed above in connection with field 312 in
The price rating data 412 may be calculated and updated in real time on the basis of the data in fields 402-410. This may be done in substantially the same manner as the above described calculation of the speed rating data 314 of
It will be appreciated that the above procedure for calculating price rating data 412 effectively provides equal weights to all of the factors represented by the data in fields 402-410. Alternatively, the data in fields 402-410 may be combined additively rather than multiplicatively, and a weighting factor may be applied to one or more of the factors represented by the data in fields 402-410 to generate the rating data 412. Other procedures for generating rating data from one or more types of order destination attribute data may alternatively be used.
Some or all of the order destination attributes corresponding to the fields 402-410 may be eliminated and/or replaced with other attributes of order destinations. For example, some or all of the order destination attributes described with reference to
It should be noted that the illustrations and accompanying descriptions of databases included herein merely represent relationships between stored information. A number of other arrangements may be employed besides those suggested, including arrangements in which some or all of the specified data is located remote from the device with which it is associated herein. It is further contemplated that each of the databases may include many more records than those shown and that each record may include associated fields other than those illustrated.

In addition, the programs 210 may include software 506 to enable the trading system 102 to perform routing decisions in accordance with aspects of the present invention with respect to orders received by the trading system 102 from customers 104. The routing decision software 506 may make routing decisions based at least in part on data contained in the order destination attribute databases 212, 214. Details of operation of the routing decision software 506 will be described below.
Further, the programs 210 may include software 508 to enable the trading system 102 to perform basic order execution functions. The order execution software 508 may operate generally in accordance with conventional principles, but may be responsive to the routing decision software 506 to implement routing decisions made by the routing decision software 506.
It should be understood that the programs 210 may perform other functions and/or may include other components in addition to the software illustrated and described in connection with
As indicated at 602, the software 504 may also perform statistical analysis as required to generate and/or update the data for the order destination attribute databases 212, 214 on the basis of data either received from data source 108 or available from transactions executed by the trading system 102. As will be appreciated from the foregoing discussion of
As seen from
The user interface 700 also includes a second scrollable list 706 of order destination identifiers which may represent an ordering of at least some of the order destination identifiers of the current displayed first scrollable list 702. An order destination identifier that does not currently appear in the second scrollable list 706 may be added to the second scrollable list 706 by selecting with a cursor (not shown) the order destination identifier in the first scrollable list 702 and then actuating “add” button 708. An order destination identifier that currently appears in the second scrollable list 706 may be removed therefrom by selecting the order destination identifier in the second scrollable list 706 and then actuating “remove” button 710.
The relative positions of the order destination identifiers in the second scrollable list 706 may be changed by operation of the “up” button 712 and the “down” button 714. More specifically, the position of an order destination identifier that is not at the top of the second scrollable list 706 may be moved up by one position by selecting the order destination identifier and actuating the up button 712. The order destination identifier may be moved up by more than one position by repeated actuation of the up button 712. Similarly, the position of an order destination identifier that is not at the bottom of the second scrollable list 706 may be moved down by one position by selecting the order destination identifier and actuating the down button 714. The order destination identifier may be moved down by more than one position by repeated actuation of the down button 714.
In some embodiments the values of trigger data 312, 410 in databases for securities traded on the market selected by the pull-down menu 704 may correspond to the positions of the respective order destination identifiers in the second scrollable list 706 corresponding to the selected market. In other embodiments, the user's desired preferences among the order destinations, as represented by the order of listing of corresponding order destination identifiers in the second scrollable list 706, may be implemented by other or additional ways besides the trigger data 312, 314. In still other embodiments, an interface (not shown) may be provided to allow the operator to explicitly enter the data for the trigger data fields 312, 410.
As indicated at 800 in
As indicated at 802, the trading system 102 may parse the order received at 800 to detect the data contained in the order and to determine how to proceed with processing the order.
As indicated at 804, the trading system may receive or access data that indicates current order book conditions at the various order destinations for the security specified in the order. This data may be received via the data source 108 and may be buffered in an order book database, which is not shown.
As indicated at 806, the trading system may access a relevant one of the databases 212 or 214. Details of this process will now be discussed with reference to
As indicated at 900 in
Considering again the determination made at 900, if it is found in making that determination that there is no dedicated database 212 for the security specified in the order, then, as indicated at 908, the same determination is made as was discussed in connection with 902. That is, it is determined at 908 whether a price rating database or a speed rating database is to be accessed. This determination may be made on the basis of customer preference, and/or on some other basis, as discussed in connection with 902. If it is determined at 908 that a price rating database should be accessed, then the trading system may access the “generic” price rating database 214 (exemplified in

The flow diagrams shown in
In embodiments described above, the trading system 102 stores some order destination attribute databases that include so-called “speed rating” data and other order destination attribute databases that include so-called “price rating” data. However, in other embodiments of the invention, such databases may be combined and/or a single rating may be provided that is indicative of relative merit of order destinations with respect to both speed of execution and price performance. In other embodiments of the invention, either one of the speed rating databases or the price rating databases may be omitted. It should also be understood that in any one or more of the databases described in this paragraph, the numbers and types of order destination attributes upon which speed, price or other ratings are determined may be varied from the numbers and types of order destination attributes included in the example databases illustrated in
In some embodiments, both current order book conditions of the order destinations and order destination attributes and/or ratings such as those described with reference to
In some embodiments, routing decisions in accordance with the invention may be made with respect to all orders received by the trading system. In some embodiments, routing decisions in accordance with the invention may be made with respect to some but not all orders received by the trading system.
The present invention has been described in terms of several embodiments solely for the purpose of illustration. Persons skilled in the art will recognize from this description that the invention is not limited to the embodiments described, but may be practiced with modifications and alterations limited only by the spirit and scope of the appended claims.
